From GOLD TIPS SITE

Compound Bows - With Release Aid
Note: With a compound bow and release aid it is acceptable to use a shaft that is stiffer than indicated on the selection chart. This is particularly true if you want to shoot a larger diameter shaft for target and 3-D archery. When in doubt, choose a stiffer arrow shaft.

1. For compound bows with IBO speed rating between 290-315 FPS shot with a release aid, use the selection chart as specified.

2. For compound bows with IBO speed rating between 315-350 FPS shot with a release aid, choose at least one box to the stiffer side (to the right) for your recommended arrow. Example : If your draw weight is 72 Ibs and your arrow length is 29", select a shaft from group number five.

3. For compound bows with IBO speed rating under 290FPS shot with a release aid, choose at least one box to the weaker side (to the left) for your recommended arrow. Example : If your draw weight is 63 Ibs and your arrow length is 27", select a shaft from group number 2 or 3.
